ELECTRIC SWITCH.

To all who/u it may conce/rn B'e it knownthat I, lViLLIAn l). T Hnoor, a citizen of the United States, and a vresident of the city of Norwich, in the county of New London and lState of Connecticut, have invented a new and Improved Electric Switch, of which the following isav full, clear, and exact description,

This invention relates to improvements in electrlcswitches, anobject of the mventlonl being to provide a quick acting switch operated by a laterally movable or slide member and which can be utilized'for higher currents.

A further object is to provide 'a switch of the character stated which can be manufactured and sold at an extremely low price, which will be strong and durable in use and which will most efectually perform the function for which it is intended.

With these and other objects in view, the invention consists in certain novel features of construction i and combinations and arrangements of parts as will be more fully vhereinafter described and pointed out in the claims.

In the accompanying drawings: i Figure 1 is a view inlongitudinal section illustrating my improved switch.

Fig. 2 is a view in section on the line 2-2 of Ff'g. 1.

Fi 3 is an enlarged view in section on thelme 3-3 of Fig. 1.

lrepresents a porcelain box and 2 a wall.v

plate secured thereto by' .means of screws 3.' The bonr is provided in its ends with two pairs of dia/gonally arranged contacts 4 secured'- in the box 1 by means of screws' 5. A longitudinally' positioned guide strip 6 is secured to the `under face of the plate 2y and spaced therefrom, and a sliding plate 7 is located between the plate 2 and'strip .6 and serves to close la slot 9 in plate 2.

. A. button 10 preferably of the corrugated 'bar shapeshowm' 4is'movable against the .outer face of plate 2 and extendsacross the.

slot 9. This button 10 is provided with a tenon 11 which extexds through the slide plate 7 and .is movable in a longitudinal slot 12 in guide strip 6,.

The guide strip'G is made with parallel l bracket arms 13, 13, having central recesses 11 in their, free ends, and also prof vided with lugs- 15 at the edges of their'.

free ends forming shoulders orstops.

A bail 16 is provided at its ends with -in- Specification' of Letters Patent.

swing the end or spring 18 past thepivotal connection of lugs 17 in recesses 145 and in so doing the'sprmg will be yunder tension and wlll quickly swlng the bail 16 vto its other extreme position.v The stops 15 limit the movement of the bail and it is of course to be understoodfthat when the bail is in one posltion the switch arms 19 engage the contacts lstand when in the other extreme .v

position the circuit is open.

The ,operation` of the switch arms is therefore controlled by the spring which insures a quick action andv the movement of the button operates to change the angle of v the spring and cause itto opera-te vto swing ,the bail and change the position of the switch arms.

Various slight changes might be madev in Vthe general form of the parts described without departing from myiniention, and hence l do not limit myself to the precise details set"=forth, but consider myself at lib erty to make such slight chan es and alterations as fairly fall within t c spirit and scope of the appended claims.

l claim:
